Here is the assembled radar sitting atop a beautiful Lorenzo d'Alessandro laser-cut collar. The radar is obviously heavier than an acrylic radar, but it places no strain of any kind on the collar. The d'Allessandro collar, I should point out, is made incredibly sturdy by hidden vertical reinforcing rods on the interior. It is the perfect collar for my aluminum radar. The fine rubber bubble lifter is a Dewey Howard creation. Look closely, and you can see the gentle radius on the top corner of each vane. A fine craftsman touch added by my machinist.
